Here is the finished backing. I ended up "hemming" just the worst small section that had a 1/4" fold and left the rest alone. The front turned out okay, and that is really the only part that matters for this quilt since it's not going to be judged, just displayed.
Here is a thread on the front if you're interested in seeing that:

I'm proud of myself for not pointing out the disappointing back in that thread even though I wanted to confess my sins.
I don't know why we all so desperately want to point out our quilt's flaws.
